Frequently Asked Questions

Four product families, all built around the same core: LED emergency drivers, emergency luminaires (including recessed downlights and twin-head fittings), exit and escape sign luminaires, and LiFePO4 battery packs. Because drivers and packs are made in the same facility as the luminaires, the battery is matched to the actual discharge curve of the driver rather than picked from a catalogue. That is the main practical difference between buying a system from one factory and assembling it from three suppliers.

A maintained luminaire is lit continuously and stays lit when mains power fails — it behaves like a normal light that also happens to be an emergency light. A non-maintained luminaire is dark in normal operation and only lights up on mains failure. Which one to use is decided by the escape route, not by preference. Corridors and rooms that are occupied during a power cut generally need maintained; escape routes that are normally lit by other fittings can use non-maintained, provided the emergency illuminance requirement is still met along the whole route.

A self-contained luminaire carries its own battery and charge circuit inside the fitting; a central battery system puts the batteries in one cabinet and distributes a protected supply to many luminaires. Self-contained is simpler to install, has no single point of failure, and suits buildings where running protected cabling is expensive. Central battery wins on maintenance: batteries sit in one accessible place and testing is centralised, which is why large hospitals and airports often prefer it. The deciding question is usually not cost but who will maintain the batteries for the next ten years.

From 3W to 300W, which covers single downlights and exit signs at the low end and higher-output drivers or central-system modules at the top. Within that range the limiting factor is usually not the driver itself but the battery: at fixed duration, required battery capacity scales roughly with load, so a very high output at a long duration pushes the pack size and the housing volume up quickly. Send the load and the duration you need and we will tell you whether the combination is feasible in the housing you have in mind.

Yes — packs are supplied separately from the luminaire, which is normally much cheaper than replacing a whole fitting at end of battery life. One practical request: at installation, record the model, voltage, chemistry and connector type of the pack, and keep it with the as-built documentation. That record is what lets someone order the correct pack five years later, when the original purchase order is no longer easy to find.

On mains failure a full-power driver keeps the luminaire at its normal output; a reduced-power driver deliberately lowers the output so a smaller battery can hold the duration. If a 40W luminaire runs at 3W in emergency mode instead of 40W, the required battery capacity drops substantially, which lowers unit cost, weight and housing size. Use reduced power for escape-route illumination, where the requirement is visibility of the route; use full power where a task has to continue during the outage.

You need three numbers: the total connected LED load in watts, the required emergency duration in minutes, and the forward voltage range of your fixture's LED string. Battery capacity scales roughly linearly with load multiplied by duration, so those three values are enough to size the pack and quote. If you also know the ambient temperature range on site, send it — a pack sized at 25°C may need derating in an unheated space.

LiFePO4 generally gives around twice the cycle life and better thermal stability, which matters when the pack sits inside a warm luminaire housing or a ceiling void. Ternary lithium offers higher energy density at a lower unit cost. For fittings that nobody will revisit for years, LiFePO4 is usually the better calculation. For cost-sensitive high-volume tenders, compare total cost per expected service year rather than unit price — the cheaper cell chemistry is rarely cheaper over a ten-year maintenance cycle.

It is the minimum time a luminaire maintains its declared emergency output, starting from a fully charged battery at the rated ambient temperature.

That last clause is the one buyers skip. Duration measured at 25°C does not predict behaviour in an unheated car park in winter, because usable battery capacity falls as temperature drops. If your installation includes cold or hot extremes, ask for duration data at those ambients rather than only at room temperature.

Commonly cited figures are 1 hour or 3 hours depending on building type and occupancy, and some jurisdictions specify 90 minutes. These requirements come from local building and fire codes, not from the manufacturer.

Confirm the figure with your local authority or specifying engineer before ordering. A supplier who quotes a duration requirement without asking which country and which building type you are working in is guessing.

Transfer time is the gap between mains failure and the emergency output reaching its full level. A gap below roughly 0.5 seconds is generally not perceived as a blackout by occupants; longer gaps are, and in a space with movement or machinery that moment of darkness is when incidents happen.

Check the figure on the specific model's datasheet rather than on a company brochure — transfer time depends on the driver circuit and can differ between series.

Usually yes, provided the input arrangement matches. Send your fixture's rated power, LED forward voltage range and driver topology (constant current or constant voltage) and we confirm compatibility before you commit.

Mismatches are most common when a constant-current LED stage is fed from a driver expecting a constant-voltage input, or when the fixture's internal driver is not bypassable. Both are identifiable from a photo of the existing driver label and a wiring sketch.

IP65 is the usual requirement for underground parking and tunnels, because it covers both dust ingress and water jets — and those spaces get washed down.

Impact resistance matters just as much in vehicle areas, so ask for the IK rating alongside the IP rating. A cracked diffuser is a mechanical failure, not a sealing failure, and no IP rating protects against a vehicle strike.

DALI interfaces are available as an option on selected models. Where automatic self-test logging is required, an addressable system is generally the better route than manual testing or RF remote control, because results are recorded automatically and exceptions can be reported instead of discovered.

Tell us the control protocol your building management system uses and we confirm which models support it before quotation.

The categories that appear in almost every project: escape routes and corridors, stairwells, exit doors and the signs above them, open floor areas above a certain size, lifts and their lobbies, plant and switch rooms, car parks, and any room without borrowed light.

The trigger is usually occupancy plus the absence of daylight, not the building type. A storage room with no window needs it even if the building is classified as a warehouse.

Three things dominate in warehouses: high mounting heights, long escape distances, and racking that blocks sight lines.

That combination usually calls for higher-output luminaires over the aisles, exit signs placed so they stay visible from within the racking rather than only from the main aisle, and careful attention to whether the fitting can be reached for testing without hiring a scissor lift. The third point is a maintenance cost decision disguised as a product decision.

The luminaire is rarely the problem; the battery is. Usable capacity falls as temperature drops, so a duration figure measured at 25°C will not hold in a freezer or an unheated underground car park in winter. Practical measures: ask for duration data at your actual low temperature, consider locating the battery outside the cold zone where the design allows, and specify LiFePO4 rather than a chemistry with poorer low-temperature behaviour. Condensation during defrost cycles also argues for a proper IP rating, not just a splash-resistant one.

These are usually aesthetics-sensitive projects, so the emergency function is designed into fittings that look like ordinary lighting: recessed downlights along corridors, exit signs with slim profiles, and self-testing units so a facilities team does not have to walk the whole building every month. Where a project has a suspended ceiling, the two questions worth settling early are the ceiling void depth for the emergency module and whether the void stays accessible for the battery replacement that happens years later.

CE is a manufacturer's declaration that the product meets the applicable EU directives — it is not a certificate issued by a third party, so "we have CE" means little on its own. What to request: the EU Declaration of Conformity naming the specific model, listing the directives and harmonised standards applied, signed and dated, plus the test reports behind it. If a supplier cannot produce these for the exact SKU you are buying, that is the red flag — not the absence of a certificate number.

At company and product level we document CE (LVD and EMC), RoHS, CB through a TÜV certification body, and ISO 9001:2015 quality management. Standards applied across the range include EN 60598 for luminaire safety, EN 61347 for control gear, EN 1838 for emergency lighting application, EN 62471 for photobiological safety, and EN 62386 where DALI control is used. Documents are issued per SKU rather than generically, so ask for the declaration and test reports covering the exact model you intend to buy. RoHS test reports and packaging compliance reports already held can be downloaded from the Downloads section of this site.

A CB certificate states that a product has been tested to IEC standards by a National Certification Body participating in the IECEE CB Scheme. Because member countries recognise CB test reports, it shortens the route to national approval in many markets instead of requiring full retesting. It is not a substitute for national marking — a CB report is an input to local approval, not the approval itself.

The commonly applied set: EN 60598 for luminaire safety, EN 61347 for control gear, EN 1838 for emergency lighting application requirements, EN 62471 for photobiological safety, and EN 62386 where DALI control is used. Which of these apply depends on the product configuration, so a statement listing all five is not the same as evidence that all five were tested on your model. Ask for the test report list by standard.

The UK operates a conformity marking system separate from CE. Requirements have changed several times and depend on product category and the current transition arrangements, so any statement about it ages quickly. Verify against the UK government's currently published guidance, or with your importer, before shipping. Do not rely on a supplier's summary of the rules — including ours.

Routinely requested: the UN38.3 test summary, a Safety Data Sheet (SDS/MSDS), and for air transport a lithium battery handling label plus the shipper's declaration. Some carriers additionally ask for a transport classification report. Requirements are set by the carrier and the destination country, and they change. Confirm with your freight forwarder for each shipment rather than assuming the last set of documents still applies.

A battery management system monitors cell voltage, current and temperature, and disconnects the pack when a value leaves the safe window. Typical protections cover over-charge, over-discharge, over-current, short circuit and temperature fault. For emergency lighting the interesting part is not the list but the recovery behaviour: a pack that latches off after a fault needs someone to notice it, whereas a self-testing luminaire that reports the fault turns a silent failure into a work order.

Yes. EN 62471 classifies lamps and lamp systems into risk groups according to optical radiation hazard. For LED emergency products the result is usually in a low risk group, but the classification has to be documented for the specific product rather than assumed for the whole category. Ask for the EN 62471 report by model, particularly for high-output or close-viewing applications such as desk-level or wall-mounted units.

EN 1838 is the European standard that specifies requirements for emergency escape lighting and standby lighting: illuminance on escape routes and in open areas, uniformity, duration, and the requirements for high-risk task areas. It is referenced by many national building codes, which is why a product can comply with EN 60598 (safety) and still fail a project — luminaire safety and lighting application requirements are two different questions.

The General Product Safety Regulation requires products to be identifiable and traceable, with manufacturer details and the safety information needed to use them correctly. Specific labelling depends on product category and sales channel, and the details have been refined since the regulation took effect. Verify against current EU guidance or with your legal adviser, and treat the label artwork as a project deliverable that needs sign-off rather than a detail to settle at printing time.

Inquiry data is stored to answer your request and for follow-up related to it. It is not sold. If you want it deleted, say so in the inquiry or reply to any message from us and ask for deletion — you do not need to give a reason. See the Privacy Policy on this site for the detail.

Yes. Logo printing, private-label packaging and customised instruction leaflets are part of the OEM service. Send vector artwork (AI, EPS or SVG) rather than a screenshot, and tell us the substrate: pad printing and laser marking behave differently on painted metal and on ABS, and the method choice affects both appearance and unit cost. For packaging, include the barcode and any mandatory importer information at artwork stage — adding it later usually means reprinting.

Housings can be produced to RAL references. Give the RAL code at quotation stage, because colour matching affects both surface preparation and minimum quantity — a non-standard colour is usually a batch process, not something that can be sprayed on a single unit economically. If the colour is critical to a project's appearance approval, ask for a physical sample of the actual finish rather than judging from a screen rendering.

MOQ depends on how far the request moves from a standard configuration. Standard models can often be supplied in small quantities for evaluation; a customised housing, non-standard colour or modified circuit carries a higher minimum because it involves setup and a production batch. The useful way to ask is by describing the change: "same housing, different logo" and "new housing, different battery" have very different minimums. Send the requirement and we will state the MOQ for that specific change instead of quoting a number that does not apply to your case.

Linkage with fire alarm systems can be integrated on request. Provide the protocol or contact interface your system uses — a dry contact, a specific bus protocol, or a vendor-specific interface — and our engineering team confirms feasibility before quotation. Worth deciding early: whether the requirement is only "switch to emergency on alarm" or also "report luminaire status back". The second one turns it into a monitoring project and changes the electronics.

Small-batch customisation is typically around 15 days, in line with the customisation lead time published on this site. Rush orders can be dispatched in 2 to 5 days where the existing configuration allows it — that is, when the change is a label, a package or a setting rather than new tooling. Timing is always confirmed against the actual production schedule at order placement, not against the standard figure in a brochure.

Mainly labour rates, component sourcing proximity and production scale. But unit price is the wrong comparison. Add freight and duty, the battery replacements expected during your project life, and the labour cost of getting to the fittings for testing. A cheaper luminaire that has to be replaced mid-contract rarely saves money, and one that is difficult to access for testing costs more every year it stays installed.

Generally yes. Mixed combinations can work, but a third-party battery pack with different charge-termination behaviour will often shorten service life — the pack is charged by a circuit designed for a different cell, and the mismatch shows up two or three years later rather than at commissioning. Buying both from one supplier also concentrates warranty responsibility with a single party, which matters more than it sounds when a project has a defect claim and three suppliers pointing at each other.

Six items make the difference: the target model or a photo of what you need; quantity per model; destination country or port; whether you want FOB or DDP; whether the requirement is standard or customised; and your target delivery date. Without these, any quote you receive is a guess — and a guess that has to be re-quoted later costs you more time than the two minutes it takes to send the details now.

Smaller accounts are welcome, and some models can be supplied in single units for evaluation. MOQ varies by model, so the useful thing to state is your realistic first-order quantity rather than an aspirational one. We would rather tell you what we can do at that volume than quote against a number you will not actually place.

Off-season typically around 15 working days; peak season allow up to about 30 days. Small-batch customisation is typically 15 days, and rush orders can ship in 2 to 5 days when the configuration allows. Every timing is confirmed per order against actual production load. When planning a project schedule, ask for the peak-season figure for the specific model — a lead time quoted for a standard model in low season is the number most likely to disappoint you later.

FOB, CIF, CFR, EXW, FCA and DDP, depending on your preference and destination. Buyers new to importing often find CIF or DDP simpler because the freight is handled for them; FOB gives more control over freight cost and carrier choice, which matters once volumes are regular. DDP is convenient but check who is recorded as importer of record, because that determines who carries customs compliance responsibility.

T/T, L/C at sight, D/P, D/A and PayPal. Standard practice for a new account is a deposit with the balance before shipment; terms for repeat accounts are agreed case by case. For a first order, the payment structure worth negotiating is not the percentage but the milestone: link the balance to a document you can verify — a passed pre-shipment inspection, or photos of the packed goods with the shipping marks — rather than to a date.

Yes. Brazil and Chile are among our regular markets, alongside Germany, the United Kingdom and Poland; overall we serve customers in more than 30 countries. For South American destinations, lithium batteries need the correct dangerous-goods documentation and the destination country may have additional import requirements. Confirm the paperwork with your forwarder before booking space, since re-booking after a documentation problem is where schedules usually slip.

You should get notice before the original ship date, with a revised date and the reason. That is a commitment worth writing into the order confirmation with any supplier, because a realistic schedule depends far less on the promised date than on how early you learn about slippage. A week of warning lets you move a site programme. A week of silence followed by a month of delay does not.

Mixed containers are common and practical, particularly for distributors who need breadth rather than depth. Confirm the per-model MOQ and the production scheduling at quotation stage, because some configurations are made to order rather than held in stock — a mixed order made entirely of to-order items takes longer than the same volume of stock items. Packing marks per model also need to be agreed early so the container can be unloaded and sorted at destination.

Batteries are warranted for 3 years and all other parts for 5 years, which is the warranty statement published across this site. Coverage applies to manufacturing defects under normal use. Battery capacity fade is assessed separately, because how fast a pack ages depends heavily on site temperature and how deeply it cycles — a pack in a hot ceiling void will not reach the same service life as one in a conditioned corridor.

LiFePO4 packs commonly reach 2,000 or more charge/discharge cycles before hitting the replacement threshold. In emergency lighting that number rarely maps directly to years, because the pack spends most of its life on float charge and only cycles during tests and outages — so calendar ageing and ambient temperature dominate. Ask for cycle life at your operating temperature, not the headline figure at 25°C, and plan battery replacement as a scheduled cost rather than a failure event.

Document the fault first: photos or a short video of the failure, the model and batch code from the label, the installation date, and a description of the site conditions. Then contact your original contact point. Resolution routes are agreed at the time of purchase and typically take one of three forms: replacement parts in the next shipment, credit against a following order, or in the case of a systematic defect, a joint investigation with the batch traced. Having the batch code available is what makes the third option possible.

Replacement packs are supplied separately, which is normally far cheaper than replacing a complete fitting at end of battery life. The practical risk is traceability, not availability: after five years, the original purchase order is hard to find and the label may have faded. Record pack model, voltage, chemistry and connector type in the as-built documentation at installation, and a replacement order becomes a two-line email instead of an investigation.

Frequency is set by local regulation, and a common pattern is a short monthly function check plus an annual full-duration discharge test. Requirements differ by jurisdiction, so confirm the interval with your local authority. Whatever the interval, the record matters as much as the test: an inspector will ask for evidence, and a system that logs results automatically is worth more than one that depends on someone filling in a sheet.

Three routes: RF remote-controlled units triggered from floor level with a handheld transmitter; self-testing units that run and record their own discharge cycles; and addressable (for example DALI) systems reporting to a central point. For larger sites, the automated options usually win on lifetime cost, because they remove the labour of manual testing and — more importantly — remove the temptation to skip it. On a small site with a dozen fittings, a remote control is often enough.

Three checks prevent most installation rework: that the ceiling void is deep enough for the emergency module; that the void stays accessible for the battery replacement that will happen years later; and that the cut-out diameter matches the ceiling type, including any fire-rated or moisture-rated ceiling requirements. On projects with many identical fittings, confirm one installation completely before the batch goes in — the cost of changing a decision after 200 fittings are mounted is not the fittings.

The three most common causes: a battery already past its service life, a fitting whose IP rating was too low for its environment so moisture reached the electronics, and testing that was never performed so the degradation stayed invisible until it mattered. All three are preventable, and none of them is fixed by buying a better luminaire next time. Schedule battery replacement, specify the IP rating the space actually needs, and keep test records.

Follow the applicable national standards and the luminaire's installation instructions. The replacement must match the specified chemistry, voltage and connector — a lithium pack is not interchangeable with a Ni-Cd pack even when the shape and terminal spacing fit. If there is any doubt about the isolation procedure or the pack specification, have a qualified electrician do it. The failure mode of a mismatched lithium pack is not a dead light; it is a thermal event.

Ask for three things and verify each of them independently:

1. A business licence whose registered scope includes manufacturing, not only sales or import-export. 2. A factory audit report, or a live video walk-through of the SMT line, assembly line and ageing test area. A live call is harder to stage than a photo set. 3. Recent shipping records for your product category, with the destination country visible.

Then cross-check the factory address on the licence against the address used on the supplier's own website and quotation sheet. A mismatch is worth resolving before you pay a deposit.

Six questions separate a capable supplier from the rest:

1. Which standards were actually tested, and by which laboratory? 2. Can you issue the EU Declaration of Conformity naming this exact SKU, rather than a generic company certificate? 3. What is the battery cycle life in cycles, not in years? 4. What are your real lead times in peak season? 5. What is the MOQ for a customised version? 6. Who handles warranty claims in my market, and how?

If any answer is vague, ask for it in writing. A supplier who cannot put numbers on paper today will not put them on paper when a project is late.

To be precise: JiangMen Anshine Technology Co., Ltd. was registered in 2025, while our founding team has about 20 years of experience in the emergency lighting industry. Anshine has worked in emergency lighting for about 20 years, focused on LED emergency drivers, emergency luminaires, exit signs and battery packs. That matters for one practical reason: emergency products are judged years after installation, when a battery reaches the end of its service life. Longevity in this category is mostly about how many battery and charge-circuit generations a factory has already been through.

The manufacturing base is 3,000 m² or more, with 5 production lines and a dedicated production and quality team of about 30 to 50 people. Covered power range runs from 3W to 300W across drivers, luminaires and battery packs. Capacity for a specific order is always confirmed against the current production schedule rather than quoted from a brochure figure. If you need a monthly capacity commitment for planning, ask for it in writing with the model mix attached.

Yes. Both are welcome — either a third-party audit or a scheduled live video walk-through of the production and test areas. We would rather show the line than describe it, because the questions that matter (how ageing tests are recorded, how battery packs are matched to drivers, how finished goods are sampled) are only answerable by looking. Certificates and test reports are available on request, and the documents held on this site can be downloaded directly from the Downloads section.
